Ionic has released ionic-angular 3.7.0 and @ionic/app-scripts 3.0.0, introducing several enhancements and bug fixes aimed at improving app performance and the developer experience. The ionic-angular 3.7.0 update supports Angular version 4.4.3, incorporates new CSS features to accommodate the iPhone X, and provides bug fixes and improvements. The @ionic/app-scripts 3.0.0 release features the integration of the Angular team's build optimizer tool, ngo, which enhances app performance by reducing size and improving boot speed under certain conditions. The updates are largely drop-in replacements, though custom webpack configurations may require adjustments. These releases are part of Ionic's ongoing efforts to transition towards web components with the upcoming ionic-angular 4.0.0, facilitated by the use of Stencil, to enhance app boot speed and runtime performance without significant disruptions to existing apps.
